Abstract
PURPOSE: To perform color developing well by disposing a plurality of developing powder containing vessels to a developing sleeve and using a cooling unit of specific constitution.
CONSTITUTION: The magnetic brush developing device is constituted by a developing sleeve 51, a plurality of developing units 52 thru 54 disposed around the same and a cooling unit 55 consisting of a magnet roll 93 approaching to and detaching from the developing sleeve 51 and a housing 95. Then, the developing powders of yellow, magenta and cyan in the developing powder containing vessles 60, 70, 80 agitated by vane wheels 62, 72, 82 are attracted to developing sleeves 61, 71, 81 by magnetic force, after which they are attracted on the developing sleeve 51 in brush form to develop the charge images of a photosensitive drum 1, after which they are scraped down into the vessels 60, 70, 80 by scraping-off plates 63, 73, 83, and further they are attracted and removed by the magnet roll 93 approached to the developing sleeve 51, whereby mutual mixing is prevented.
